Clematis plant named ‘Evipo039’

ABSTRACT

A new  Clematis  plant with profuse, light violet flowers and early flowering habit. The variety successfully propagates from softwood cuttings and is suitable for cultivation commercial nursery culture culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.

Botanical classification:

Genus: Clematis.

Species: viticella.

Variety denomination: ‘Evipo039’.

SUMMARY OF THE CLAIMED PLANT

The present discovery constitutes a new and distinct variety of clematis plant which was discovered in a cultivated area.

The new clematis plant resulted from a naturally occurring mutation of unknown causation on a branch of ‘Fairy Blue’, U.S. Plant Pat. No. 18,223. The resulting mutation was selected and evaluations were conducted on the resulting clematis plants in a controlled environment.

The clematis plant of the present discovery is distinguished from the original clematis ‘Fairy Blue’ mainly by differences in the flower center. ‘Evipo039’ has an arrangement of broad inner tepals at the flower center, while ‘Fairy Blue’ has a flower center of more narrow, spindly inner tepals.

The objective of the selection of this clematis plant was to create a new and distinct variety for nursery culture with unique qualities such as:

-   -   1. Profuse light purple flowers with distinct center;     -   2. Long flowering season;     -   3. Propagates and flowers more reliably than most double         cultivars;     -   4. Well suited to container nursery culture.

This combination of qualities was lacking in clematis plants that were in commercial cultivation and the qualities have been substantially achieved in the new variety.

‘Evipo039’ was evaluated by Mogens N. Olesen and Raymond J. Evison in their clematis development program in the Channel Islands, United Kingdom in 2002. Asexual reproduction of ‘Evipo039’ by means of vegetative cuttings and traditional layering was first performed by Mogens N. Olesen and Raymond J. Evison in the nursery during the summer of 2002. This initial and subsequent asexual propagations have demonstrated that the characteristics of ‘Evipo039’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘Evipo039’, as observed in its growth throughout the flowering period in glasshouses in the Channel Islands, United Kingdom. Observed plants were cultivated for a period of 24 months in 2 liter containers. Certain phenotypical characteristics of the variety may vary under different environmental, cultural, agronomic, seasonal, and climatic conditions. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison two physical characteristics of the clematis variety ‘Fairy Blue’ are compared to ‘Evipo039’ in Chart 1.
